The Torah is very specific on the basic requirements...the most basic is that the Jewish Messiah is a man...not a demi-god, or any version G-d becoming man (”God is not a mortal” (Numbers 23:19)). If you recall, G-d gave us Gentiles our instructions in the time of Noah, so we have long been covered by his love...best to you...magritte
As far as God not being Mortal...well Christ indeed rose from the dead...so death itself had no power over Him. What love that God would send us Salvation for that which we could not accomplish apart from Him.. Amazing Grace comes to mind.
